Description

Die Erfindung betrifft eine wiederablösbare, selbstklebende Vorrichtung mit Anfaßhilfe, die rückstandsfrei durch Ziehen an der an ihr angeordneten Klebfolie in Richtung der Verklebungsebene aus ihrer Verklebung wieder gelöst werden kann.The invention relates to a removable, self-adhesive device with a touch aid, the residue-free by pulling on the adhesive film arranged on it Direction of the bond plane from its bond again can.

Solche Vorrichtungen, insbesondere Haken sind bekannt. So beschreibt DE 42 33 872 C2 einen wieder ablösbaren, selbstklebenden Haken, der mit einer auf Zug entklebenden Klebfolie ausgerüstet ist und der als

Figure 00010001
tesa® Power-Strips mit Haken" im Handel erhältlich ist.Such devices, in particular hooks, are known. For example, DE 42 33 872 C2 describes a removable, self-adhesive hook that is equipped with an adhesive film that removes tension and that as
Figure 00010001
tesa® Power-Strips with hooks "is commercially available.

Auch aus WO 94/21157 ist ein solcher Haken bekannt, der sich vom vorgenannten insbesondere durch den Einsatz einer solchen Klebfolie unterscheidet, die hochdehnbar und zugleich nicht rückstellend ist.Such a hook is also known from WO 94/21157, which differs from the aforementioned differs in particular by the use of such an adhesive film is highly stretchable and at the same time not resilient.

Bei dem praktischen Einsatz derartiger Vorrichtungen können jedoch Probleme auftreten, insbesondere beim späteren Ablösen.Problems may arise with the practical use of such devices occur, especially when detaching later.

Nachteilig bei den bislang bekannten Problemlösungen ist insbesondere, daß das Lösen der Klebbindung durch Ziehen der Klebestreifen im wesentlichen in der Verklebungsebene geschehen muß, wobei Fehlanwendungen für den unerfahrenen Nutzer vorprogrammiert sind.A disadvantage of the previously known problem solutions is in particular that essentially loosening the adhesive bond by pulling the adhesive strips the gluing level must be done, misuse for the inexperienced Users are pre-programmed.

In vielen Fällen hat es sich gezeigt, daß die Ursache von Reißern darin besteht, daß der Anwender den zu lösenden Gegenstand während des Löseprozesses mit hohem Kraftaufwand gegen den verklebten Gegenstand drückt. Hierdurch wird die zum Herausziehen des Klebebandes aus der Klebfuge notwendige Kraft derart erhöht, daß die Reißfestigkeit überschritten wird, mit der unerfreulichen Konsequenz für den Anwender, daß das Klebeband reißt und die Verklebung nicht mehr rückstands- und zerstörungsfrei gelöst werden kann.In many cases it has been shown that the cause of tears is that the user with the object to be solved during the release process high force pushes against the glued object. This will the force required to pull the adhesive tape out of the adhesive joint increased that the tensile strength is exceeded, with the unpleasant consequence for the user that the tape breaks and the adhesive does not can be solved more residue-free and non-destructively.

Aufgabe der vorliegenden Erfindung war es, die vorgenannten Nachteile zu überwinden.The object of the present invention was to overcome the aforementioned disadvantages overcome.

Gelöst wird diese Aufgabe erfindungsgemäß durch eine wiederablösbare, selbstklebende Vorrichtung mit einer Platte, deren Seiten und/oder Vorderseite ggf. Mittel zur Befestigung aufweisen und deren Rückseite einen Streifen einer beidseitig klebenden Klebfolie derart aufgeklebt aufweist, daß ein Ende der Klebfolie als Anfasser die Platte überragt, wobei die Klebfolie eine solche ist, daß die mit ihr erzielte Verklebung durch den Streifen streckendes Ziehen in Richtung der Verklebungsebene wieder lösbar ist, dadurch gekennzeichnet, daß die Vorderseite der Platte (1) eine Anfaßhilfe (5) aufweist, mittels der die Platte (1) beim wieder Lösen der Verklebung durch Ziehen des Streifens (7) gehalten werden kann.According to the invention, this object is achieved by a removable, self-adhesive device with a plate, the sides and / or front possibly have means for attachment and the back of a strip of has adhesive film glued on both sides so that one end of the Adhesive film protrudes from the plate as a handle, the adhesive film being such that the adhesive achieved with it by pulling the strip in the direction the bond plane is releasable, characterized in that the front the plate (1) has a gripping aid (5), by means of which the plate (1) when releasing the bond can be held by pulling the strip (7) can.

Bevorzugt ist auch eine Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Anfaßhilfe (5) zusammen mit der Platte (1) als Spritzgußteil aus Kunststoff ausgebildet ist. A device according to claim 1 is also preferred, characterized in that that the gripping aid (5) together with the plate (1) as an injection molded part made of plastic is trained.

Bevorzugt ist auch eine Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Anfaßhilfe (5) in die Platte (1) integriert ist.A device according to claim 1 is also preferred, characterized in that that the grasping aid (5) is integrated in the plate (1).

Bevorzugt ist auch eine Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Klebfolie mit oder ohne Zwischenträger elastisch oder plastisch dehnbar ist.A device according to claim 1 is also preferred, characterized in that that the adhesive film with or without an intermediate carrier is elastically or plastically stretchable is.

Bevorzugt ist auch eine Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Adhäsion der Klebfolie geringer als die Kohäsion ist, das Haftvermögen beim Dehnen der Folie weitgehend verschwindet und das Verhältnis von Abzugskraft zu Reißlast mindestens 1 : 1,5 ist, wobei die Klebefolie eine solche auf Basis von thermoplastischem Kautschuk und klebrigmachenden Harzen ist, mit hoher Elastizität und geringer Plastizität.A device according to claim 1 is also preferred, characterized in that that the adhesion of the adhesive film is less than the cohesion, the adhesiveness when stretching the film largely disappears and the ratio of peel force to tear load is at least 1: 1.5, with the adhesive film on one The basis of thermoplastic rubber and tackifying resins is with high elasticity and low plasticity.

Ein reißerfreies Wiederablösen wird demgemäß insbesondere dadurch erreicht, daß in die Platte eine Anfaßhilfe integriert ist, welche es erlaubt, die Platte über die Anfaßhiffe beim Ablöseprozeß derart mit der Hand zu fixieren, daß die Platte beim Herausstrippen der Klebstoff-Folie im wesentlichen frei von senkrecht zur Verklebungsrichtung einwirkenden Kräften bleibt.A tear-free redetachment is accordingly achieved in particular by that a touch aid is integrated into the plate, which allows the plate to be pulled over to fix the handle during the detachment process by hand in such a way that the plate when stripping out the adhesive film essentially free from perpendicular to Forces acting in the direction of adhesion remain.

Erfindungsgemäß eignen sich als Klebstoff-Folien insbesondere solche entsprechend DE 33 31 016, DE 42 22 849, DE 42 33 872, WO 92/11333 und WO 94/21157. According to the invention, adhesive films are particularly suitable DE 33 31 016, DE 42 22 849, DE 42 33 872, WO 92/11333 and WO 94/21157.

So beschreibt DE 33 31 016 A1 eine Klebfolie für wiederlösbare Klebbindungen, die es gestattet, daß eine damit hergestellte Klebbindung durch Ziehen an der Klebfolie in Richtung der Verklebungsebene lösbar ist. Mit solchen Klebfolien lassen sich hohe Klebkräfte und Scherfestigkeiten erzielen und Klebverbunde ohne weitere Hilfsmittel wieder lösen, vergleichbar dem Öffnen eines Weckglases, ähnlich wie dort die Gummidichtung am Anfasser aus der Dichtungsfuge gezogen wird.DE 33 31 016 A1 describes an adhesive film for releasable adhesive bonds, which allows an adhesive bond thus produced by pulling on the Adhesive film is releasable in the direction of the bond plane. With such adhesive films high adhesive strengths and shear strengths can be achieved and adhesive composites without further aids, comparable to opening a mason jar, similar to where the rubber seal on the handle is pulled out of the sealing joint becomes.

DE 42 22 849 C1 beschreibt eine derartige Klebfolie mit einem UV-undurchlässigen Anfasser.DE 42 22 849 C1 describes such an adhesive film with a UV-impermeable Handle.

Auch WO 92/11333 beschreibt unter anderem Klebfolien für entsprechende Anwendungen, wobei die eingesetzten Klebefolien eine geringe Elastizität bei gleichzeitig hoher Dehnung aufweisen.WO 92/11333 also describes, among other things, adhesive films for corresponding applications, the adhesive films used have a low elasticity have high elongation at the same time.

Auch doppelseitige Selbstklebebänder mit Schaumstoff-Zwischenträger, z.B. aus Polyethylen-Schaum lassen sich erfindungsgemäß einsetzen.Also double-sided self-adhesive tapes with foam intermediate carrier, e.g. out Polyethylene foam can be used according to the invention.

Generell sei zu Herstellung, Verarbeitung und Handhabung von den besonders bevorzugten Klebfolien auf DE 33 31 016, DE 42 22 849 und WO 92/11333 verwiesen.In general, the manufacture, processing and handling of the special preferred adhesive films refer to DE 33 31 016, DE 42 22 849 and WO 92/11333.

Als Platte bzw. Formkörper, insbesondere als Basisplatten eignen sich:

  • Kunststoff, Metall, Holz (beschichtet, z.B. lackiert und unbeschichtet), Keramik und dergleichen.
The following are suitable as plates or shaped bodies, in particular as base plates:
  • Plastic, metal, wood (coated, eg painted and uncoated), ceramics and the like.

Erfindungsgemäße Vorrichtungen dienen zur einseitigen Aufnahme der Klebstoff-Folie, deren andere Seite auf den ausgewählten Untergrund verklebt wird. Auf die Platte können unterschiedlichste Adapter plaziert werden, u.a. Hakenkörper. Zur Erzeugung einer hohen Verklebungsfestigkeit besteht die Plattenfläche auf der Seite auf die die Klebstoff-Folie appliziert wird, insbesondere aus einem Material, welches eine für den jeweiligen Anwendungsfall ausreichende Adhäsion zur Klebstoff-Folie aufweist. Bei der Verwendung von Haftklebemassen auf Basis von Styrolblockcopolymeren oder Acrylatcopolymeren wird hierbei u.a. vorteilhafterweise Polystyrol, schlagzähmodifizierte Polystyrole, PMMA, aromatische Polyester, Polycarbonat oder Polyamid eingesetzt.Devices according to the invention are used to hold the adhesive film on one side, the other side of which is glued to the selected surface. On the plate can be placed with a wide variety of adapters, including Hook body. The panel surface is used to create a high bond strength the side to which the adhesive film is applied, in particular made of a material, which has sufficient adhesion for the respective application to the adhesive film. When using PSAs based on Styrene block copolymers or acrylate copolymers are used here, among other things. advantageously Polystyrene, impact modified polystyrenes, PMMA, aromatic polyester, Polycarbonate or polyamide used.

Ein reißerfreies Wiederablösen wird insbesondere dadurch erreicht, daß in die Platte eine Anfaßhilfe integriert ist, welche es erlaubt, die Platte über die Anfaßhilfe beim Ablöseprozeß derart mit der Hand zu fixieren, daß die Basisplatte beim Herausstrippen der Klebstoff-Folie im wesentlichen frei von senkrecht zur Verklebungsrichtung einwirkenden Kräften bleibt. Realisierungsmöglichkeiten für eine derartige Anfaßhilfe sind u.a. die Integration eines ausklappbaren über eine flexible Verbindung fest mit der Platte verbundenen Anfassers. Eine entsprechende Anfaßhilfe kann z.B. direkt beim Spritzgießen in die Basisplatte integriert werden, jedoch auch separat appliziert werden. Eine spezielle Ausformung ist die eines auf die Basisplattenrückseite aufgebrachten Selbstklebebandes.A tear-free redetachment is achieved in particular in that A touch aid is integrated in the plate, which allows the plate to be touched using the touch aid to fix with the hand in such a way that the base plate with Stripping out the adhesive film essentially free of perpendicular to the direction of bonding acting forces remains. Realization options for a such touching aids include the integration of a fold-out via a flexible Connection firmly attached to the plate. A corresponding Touching aid can e.g. can be integrated directly into the base plate during injection molding, but can also be applied separately. A special shape is one self-adhesive tape applied to the back of the base plate.

Beim Abstrippen der Klebstoff-Folie wird die Platte über die Anfaßhilfe mit Daumen und Zeigefinger fixiert. Dadurch, daß der Fixierpunkt außerhalb des Plattenkörpers in entgegengesetzter Richtung zur Abzugsrichtung der Klebstoff-Folie liegt, wirken nur geringe Kräfte senkrecht zur Verklebungseben ein. Ein Reißen infolge zu hohen Anpreßdruckes senkrecht zur Verklebungsebene ist damit ausgeschlossen.When stripping off the adhesive film, the plate is touched with the thumb and index finger fixed. The fact that the fixing point outside the plate body in the opposite direction to the pull-off direction of the adhesive film only small forces act perpendicular to the bond plane. A tear as a result of excessive contact pressure perpendicular to the bond plane is excluded.

Im folgenden soll die Erfindung anhand von Beispielen und Figuren beschrieben werden, ohne sie jedoch unnötig einschränken zu wollen.The invention is described below with the aid of examples and figures without wanting to limit them unnecessarily.

Zum Ablösen werden die Gewebebandanfasser mit Zeigefinder und Daumen der linken Hand fixiert und die Klebfolienstreifen mit der rechten Hand in einem Winkel von < 5 Grad gegenüber der Verklebungsebene bei Separationsgeschwindigkeiten von ca. 1000 mm/min aus der Klebfuge herausgezogen. Beurteilt wird die maximal gemessene Ablösekraft und, ob sich die Klebfolienstreifen reißerfrei aus der Klebfuge wieder herauslösen lassen. Nachfolgende Versuchsergebnisse werden erhalten: Basisplattentyp vertikale Andruckkraft // maximale Ablösekraft Versuchsergebnis ohne Gewebeband ohne 9 N/cm reißerfrei ablösbar ohne Gewebeband 20 N 17N/cm reißerfrei ablösbar ohne Gewebeband 100 N > 25 N/cm Klebstoff-Folie reißt ohne Gewebeband 500 N > 25 N/cm Klebstoff-Folie reißt mit Gewebeband - 9 N/cm reißerfrei ablösbar For comparison, base plates are used, which are additionally equipped on the back of the base plate with a self-adhesive fabric tape (tesa band 4651) measuring 80 mm x 20 mm in such a way that 50 mm x 20 mm pieces of the fabric tape are glued centrally over the entire length of the base plates and the remaining 30 mm x 20 mm half-length ends are glued to themselves. A 15 mm x 20 mm fabric tape handle protrudes from each of the short edges of the base plates from the back of the base plate. Base plates modified in this way are bonded to Formica in the same way as above. For detachment, the fabric tape grip is fixed with the index finger and thumb of the left hand and the adhesive film strips are pulled out of the adhesive joint with the right hand at an angle of <5 degrees to the bonding plane at separation speeds of approx. 1000 mm / min. The maximum measured release force is assessed and whether the adhesive film strips can be detached from the adhesive joint without tearing. The following test results are obtained: Base plate type vertical pressure force // maximum release force Test result without fabric tape without 9 N / cm removable without tearing without fabric tape 20 N 17N / cm removable without tearing without fabric tape 100 N > 25 N / cm Adhesive film tears without fabric tape 500 N > 25 N / cm Adhesive film tears with fabric tape - 9 N / cm removable without tearing

Durch die Verlagerung des Fixierung der Basisplatte fort vom eigentlichen Basisplattenkörper ist die Ausübung einer vertikal auf die Verklebungsebene einwirkenden Andruckkraft weitestgehend eliminiert, so daß sich die Klebstoff-Folien mit geringen maximalen Ablösekräften und reißerfrei aus der Klebfuge herauslösen lassen.By shifting the fixation of the base plate away from the actual one Base plate body is the exercise of a vertical on the bonding plane acting pressure force largely eliminated, so that the adhesive films with low maximum release forces and tear-free from the adhesive joint let out.
